SYNOPSIS

DESCRIPTION

These routines delete the character under the cursor; all characters to the
right of the cursor on the same line are moved to the left one position and the
last character on the line is filled with a blank. The cursor position does
not change (after moving to y, x, if specified). (This does not
imply use of the hardware delete character feature.)

RETURN VALUE

All routines return the integer ERR upon failure and an OK (SVr4
specifies only "an integer value other than ERR") upon successful
completion.

Functions with a "mv" prefix first perform a cursor movement using
wmove, and return an error if the position is outside the window,
or if the window pointer is null.

NOTES

Note that delch, mvdelch, and mvwdelch may be macros.

PORTABILITY

These functions are described in the XSI Curses standard, Issue 4. The
standard specifies that they return ERR on failure, but specifies no
error conditions.
